WILLIAM F; BROWN, OF CEDARVILLE, ARKANSAS.

CHURN.

T0 all fwhom it may concern.'

Be 1t known that I, vWILLIAM F. BROWN, a citizen of the United States,residing at Cedarville, in the county of Crawford and State of Arkansas,have invented certain new and useful Improvements in Chur-ns, of whichthe following is a specification.

This invention relates to new and useful improvements in churn and icecream freezers and consists in the novel features of construction andarrangement of parts illustrated in the drawings and more particularlypointed out in the appended claim.

In the accompanying drawings z-Figure 1 is a front elevation olf myinvention. Fig. 2 is a similar view looking from the opposite end of thedevice. Fig. 3 is a vertical transverse section of Fig. 1. Fig. 4 is adetail perspective view of the agitators shown on an enlarged scale andFig. 5 is a detailview of the clamp for holding the upper end of thehollow agitator shaft in position.

Referring to the drawings for a more particular description of theinvention and which drawings are for illustrative purposes only and aretherefore not drawn to scale, 1 indicates the supporting frame or standprovided with the horizontal platform or base 2 for supporting the churnor ice-cream freezer, as the case may be.

The device further comprises a bracket 3 which is arranged in a verticalposition and is secured to the top of the supporting frame in anysuitable way. The vertical body portion l of the bracket is providedwith a suitable opening to receive the inner end of the horizontal powershaft 5 provided at its inner end with the beveled gear wheel 6 and atits outed end with the crank handle 7.

The device comprises the agitator 8 which is suitably attached to thelower end of the hollow upright agitator shaft 9, passing through thetop 10 of the churn 11 with its upper end extending through acorresponding horizontal transverse slot formed in the lower horizontalarm 12 of the bracket 3. An arc-shaped clamp 13 is pivoted at one end,as at 14, to the arm 12 of the bracket 3 and when swung into theposition indicated by Figs. 3 and 5 holds the upper end of the agitatorshaft 9 in position. The agitator 9 is provided at opposite ends withthe concave wings 15 which are curved in opposite directions. Owing tothis construction,

I provide what I may term a centrip- Specification of Letters Patent.

etal motion which throws the milk toward the center andthereby increasesthe churning power.

The device also comprises a second agitator 1G provided with theoppositely bent or curved wings 17 which is secured to the lower end ofthe solid shaft 17 at a point beneath the agitator 8. The shaft 17 exytends through and beyond the upper end of the hollow agitator shaft 9and has a beare ing in the upper horizontal arm 18 of the bracket 3. i

A beveled pinion 19 is keyed or otherwise secured to the upper end ofthe agitator shaft 17 and a second beveled pinion 20 to the upper end ofthe hollow agitator shaft 9 with a hollow sleeve 21 inclosing the upperprojecting end of the solid shaft 17 between the pinions 19 and 20. Thebeveled pinions 19 and 20 are arranged to mesh with the teeth of thegear wheel 6.

In Figs. 1 and 3, I have shown the device arranged for churning milk,but when used for freezing milk for ice-cream, an outer vessel 22 isprovided for the reception of t-he ice which fills the space 28 betweenthe outer and inner vessels.

In operation, the crank handle 7 of the power shaft 5 is turned, which,through the medium of the gear wheel 6 and beveled pinions 19 and 20keyed to the agitator shafts 17 and 9, respectively, causes said shaftswith the agitators 8 and 16 to turn or rotate in opposite directionswhich gives the maximum churning power with the minimum work applied,and enables the operator to churn the milk in a much quicker time thanthrough the use of churns now on the market.

It will be observed that the wings 17 of l the agitator 16 are arrangedat an angle with the wings 15 of the agitator 8.

A fan 24: is secured to the agitator shaft 9 for the purpose of keepingflies or other insects away from the vessel containing the milk.

From experience, I have found that in making ice-cream, the milk may befrozen in about three minutes, while about the same amount of time isrequired to churn milk into butter.

From the foregoing description taken in connection with the drawings, itis thought that the construction and advantages of this invention willbe readily understood without requiring a more extended explanation.

10 agitators, each having opposite end blades' With upwardlyextendingoppositely curved upper edges, said blades being positioned atright angles to each other, concentric shafts carrying said agitatorsand actuating means for shafts.

In testimony whereof I ailiX my signature in presence of tWo Witnesses.
